Grammarly has integrated advanced speech-to-text functionality into its mobile keyboard, allowing users to dictate text directly into any app with automatically polished, ready-to-send messages. This feature handles various languages and accents, removes filler words, and corrects grammar while preserving tone, offering a convenient alternative to traditional typing on mobile devices. The microphone activates only when tapped, ensuring user control and privacy, with audio deleted after processing.
